Why does targeted cooling of the preoptic area induce shivering, even when core body temperature is normal?

💡 Explanation

The preoptic area's cooling is interpreted by the hypothalamus as a drop in the body's set point temperature, because the hypothalamus attempts to maintain its perceived set point. Therefore, this induces shivering to generate heat and raise the core temperature back to the (falsely) perceived set point, rather than other temperature regulation mechanisms.
